Ecology

• What is a habitat

  A place where the organism lives
• What is a population

  Refers to all of the organisms of a particular species that live in the same habitat
• What is a community?

  All the populations of a different species that live together in a habitat
• What is an ecosystem?

  The interaction of a community of living organisms (biotic) with the non-living (abiotic) parts of their environment
• What is competition?

  An interaction between organisms or species in which they both try to use the same limited resources
• What is interdependence

  Where all organisms in an ecosystem depend upon one another with countless complex relationships between them all
• What are biotic factors?

  Living organisms
• What are abiotic factors?

  Non living components in an ecosystem
• What is symbiosis?

  Mutually beneficial relationship between two different species.
• What is parasitism?

  A symbiotic relationship where one organism benefits at the expense of another.
• What are the two types of sampling?

  Systematic and random
• What are the three types of adaptations?

  Structural,behavioural and functional
• What is structural adaptations

  Physical features
• What are behavioural adaptations

  How organisms behave or react
• What are functional adaptations

  Processes inside an organism (metabolism and reproductive)
• What would “thick fur” be classified as

  Structural adaptation
• What would “eating a range of food” be classified as

  Behavioural adaptation
• What would hibernation be classified as

  Behavioural adaptation due to overeating in summer and sleeping all winter, but also functional adaptations as there would be lower metabolism rates when hibernating
• What are extremophiles

  Organisms adapted to live in extreme environmenta
• What types of environments would extremophiles live in?

  high temp,salt and pressure
• What type of organisms are extremophiles

  Bacteria and archaea
• What are peat Boggs?

  Wetlands.
• What was peat used for?

  fertiliser and fuel
• What type of energy is peat

  Non-renewable
• What are peat Boggs known as?

  “Carbon sinks”
• Why is burning peat a problem?

  Releases co2 and contributes to global warming (greenhouse effect) and reduces biodiversity
• What is biodiversity

  The number of different species
